Abstract

The association between balanitis xerotica obliterans (BXO) and skin disorders is long established, however, the role of skin phototype and local trauma in its onset has never been investigated in detail. Medical records of all Caucasian children circumcised over a 6-year period were reviewed. The excised skin underwent histological examination for BXO. Children with histological diagnosis of BXO were classified as group A, whereas children without histological diagnosis of BXO were classified as group B. The Fitzpatrick phototype (FT) was obtained in all children performing a personal or family interview with regards to their sunburn and suntan experience. According to their FT, both group A and B patients were divided into two subgroups: FT 1-2, with a higher tendency to sunburn due to their low skin melanin content; and FT 3-4 with a higher tendency to tan due to their higher skin melanin content. Maneuvers of mechanical reduction of the foreskin (MRF) performed at least 5-10 times per month during the year preceding circumcision was also considered. Statistical analysis was performed using univariate and multivariate analysis. A total of 297 patients met the inclusion criteria of our study: 78 patients were classified as group A and 219 as group B. The risk of developing BXO was significantly greater in FT 1-2 patients (n=76) (odd ratio=0.232, 95% confidence interval=0.124-0.435, p<0.0001). Furthermore, those undergoing MRF (n=131) had a significantly higher risk of developing BXO (odds ratio= 5.344, 95% confidence interval=2.860-9.987, p<0.0001). Although the foreskin is not directly exposed to sunlight, this study emphasizes the role of skin phototype on the onset of BXO in circumcised individuals. Moreover, the data produced suggest should the advantages of repeated MRF be weighed against the increased risk of developing BXO, which in turn may increase complication rate of circumcision surgery.
